[0032] As shown in Figures 1 to 5, in one exemplary embodiment of the present invention, a wire harness product clamping device is disclosed. The wire harness product clamping device includes a pair of cantilevers 4 and a variety of different wire harness fixtures 6, 51 and 52. The pair of cantilevers 4 is attached to a safety cover 9 of the heat shrink machine and can be moved between a first position and a second position and can be rotated between a use state and a storage state. The multiple different wire harness fixtures 6, 51 and 52 are attached to the cantilevers 4 and clamp various wire harness products 8, respectively. In the illustrated embodiment, the wire harness item 8 typically includes a wire harness 80 and a heat shrink tube 83 fitted around the wire harness 80.

[0036] As shown in Fig. 6, in the illustrated embodiment, when the wire harness clamping device does not need to be used, the pair of cantilevers 4 are rotated from a use state to a storage state and moved from a first position to a second position. In this way, it does not take up production space and is therefore very convenient.

[0037] 1 to 6, in the illustrated embodiment, the wire harness fixtures 6, 51 and 52 include a pair of first wire harness fixtures 6. The pair of first wire harness fixtures 6 are respectively attached to the pair of cantilevers 4 and are suitable for clamping two ends of a first wire harness item (not shown), respectively.

[0038] 1 to 6, in the illustrated embodiment, the wire harness fixtures 6, 51 and 52 further include a pair of brackets 5 and a pair of second wire harness fixtures 51 and 52. The pair of brackets 5 are attached to the pair of cantilevers 4. The pair of second wire harness fixtures 51 and 52 are respectively attached to the pair of brackets 5 and are suitable for clamping two ends 81 and 82 of the second wire harness item 8.

[0039] 1 to 6, in the illustrated embodiment, the two ends 81 and 82 of the second wire harness item 8 are different from each other. The pair of second wire harness fasteners 51 and 52 are different from each other and are suitable for clamping the two ends 81 and 82 of the second wire harness item 8, respectively.

[0040] 1 to 6, in the illustrated embodiment, the bracket 5 is removably attached to the cantilever 4, or the second wire harness fixtures 51 and 52 are removably attached to the bracket 5, thereby allowing for quick replacement of the second wire harness fixtures 51 and 52. In this manner, different wire harness fixtures can be quickly replaced for clamping different wire harness items.

[0041] 1 to 6, in the illustrated embodiment, the pair of cantilevers 4 are respectively attached to the outer surfaces of the pair of side walls 91 of the safety cover 9. When the pair of cantilevers 4 is in use and moved to the second position, the pair of first wire harness fixtures 6 are respectively positioned outside the pair of side walls 91 of the safety cover 9, and the pair of second wire harness fixtures 51 and 52 are respectively positioned inside the safety cover 9.

[0042] 1 to 6, in the illustrated embodiment, the wire harness product clamping device further includes a pair of slide rails 1 and a pair of sliders 2. The pair of slide rails 1 are suitable for attachment to the outer surfaces of the pair of side walls 91 of the safety cover 9, respectively. The pair of sliders 2 are slidably attached to the pair of slide rails 1 so as to be movable along the pair of slide rails 1. One end of each of the pair of cantilevers 4 is coupled to the pair of sliders 2 so as to be movable together with the pair of sliders 2.

[0043] 1 to 6, in the illustrated embodiment, the wire harness clamping device further includes a bridge member 3. The bridge member 3 spans between the pair of sliders 2 and ensures synchronous movement of the pair of sliders 2 and the pair of cantilever arms 4.

[0044] 1 to 6, in the illustrated embodiment, the bridge member 3 includes a pair of arms 32, a cross beam 31, and a pair of mounting seats 33. The cross beam 31 is connected between one ends of the pair of arms 32. The pair of mounting seats 33 are attached to the other ends of the pair of arms 32. The pair of sliders 2 are attached to the inner surfaces of the pair of mounting seats 33 that face each other, and one ends of the pair of cantilevers 4 are connected to the outer surfaces of the pair of mounting seats 33.

[0045] As shown in Figures 1 to 6, in the illustrated embodiment, one end of the pair of cantilevers 4 is rotatably coupled to a pair of mounting seats 33, thereby enabling the pair of cantilevers 4 to rotate between a use position and a storage position.

[0046] As shown in Fig. 1 to Fig. 6, in the illustrated embodiment, a pin hole 41a is formed in one end of the cantilever 4 and the mounting seat 33. The wire harness product clamp device further includes a lock pin 41b suitable for fitting into the pin hole 41a. When the pair of cantilevers 4 is in a use state or a storage state, the lock pin 41b is inserted into the pin hole 41a to lock the pair of cantilevers 4 in the use state or the storage state. When the pair of cantilevers 4 needs to be rotated, the lock pin 41b needs to be pulled out of the pin hole 41a.

[0047] 1 to 6, in the illustrated embodiment, the wire harness clamping device further includes a pair of handles 7. The pair of handles 7 are respectively attached to the other ends of the pair of cantilevers 4 and can be actuated to move the pair of cantilevers 4 between a first position and a second position and rotate the pair of cantilevers 4 between a use state and a storage state.

[0048] As shown in Figures 1 to 6, in the illustrated embodiment, the slide rail 1 extends along a first horizontal direction and the rotation axis of the mating cantilever 4 extends along a second horizontal direction perpendicular to the first horizontal direction.

[0049] 1 to 6, in the illustrated embodiment, a limiting block 1a is provided at the end of the slide rail 1. The limiting block 1a is suitable for pressing against the slider 2 or the mounting seat 33 to limit the paired cantilever 4 to a first position or a second position.

[0050] 1 to 6, in the illustrated embodiment, when the paired cantilever 4 is moved to the first position, the bracket 5 of the paired cantilever 4 is in a position that does not interfere with the safety cover 9, and therefore the paired cantilever 4 can rotate between the use state and the storage state. When the paired cantilever 4 is moved to the second position, the bracket 5 of the paired cantilever 4 is in a position that interferes with the safety cover 9, and therefore the paired cantilever 4 is prevented from rotating between the use state and the storage state. Therefore, in the present invention, when it is necessary to rotate the paired cantilever 4, the paired cantilever 4 must first be moved to the first position.

[0051] 1 to 6, in the illustrated embodiment, when the wire harness clamping device does not need to be used, the pair of cantilevers 4 are rotated from a use state to a storage state and moved from a first position to a second position. When the wire harness clamping device needs to be used, the pair of cantilevers 4 are moved from the second position to the first position and rotated from the storage state to the use state.

[0052] As shown in Fig. 1 to Fig. 6, another exemplary embodiment of the present invention further discloses a heat shrink machine. The heat shrink machine includes a safety cover 9, a heating device (not shown), and the above-mentioned wire harness product clamping device. The wire harness product clamping device is used to clamp a wire harness product 8 and move a heat shrink tube 83 of the clamped wire harness product 8 into the inside of the safety cover 9. The heating device is used to heat the heat shrink tube 83 that has been moved into the inside of the safety cover 9.

[0053] 1 to 6, in the illustrated embodiment, when the paired cantilever 4 is in a use state, the wire harness fixtures 6, 51 and 52 are disposed below the bottom opening of the safety cover 9 so that the heat shrink tube 83 can enter the bottom opening of the safety cover 9. When the paired cantilever 4 is in a storage state, the wire harness fixtures 6, 51 and 52 are disposed above the top wall 90 of the safety cover 9 so as not to occupy production space.

[0054] As shown in Figures 1 to 6, the integrated external wire harness product clamping device of the present invention does not require the occupation of additional space, can be quickly deployed for use, and can be folded without disassembly for storage, and is therefore very convenient to use.
